Election commission chief Abdel-Moez Ibrahim announced results from the second round of three, which was held Dec. 14-15, followed by a runoff last week. The second round was held in nine provinces, and Ibrahim said turnout reached 65 percent.

Based on the results Ibrahim gave, the Muslim Brotherhood says its political party won about 86 — or 47 percent — of the estimated 180 seats up for grabs in the round.

The political arm of the ultraconservative Salafist movement, al-Nour Party, won about 20 percent of the vote.

The secular and liberal forces that largely drove Egypt’s uprising against former leader Hosni Mubarak were trounced, failing to turn their achievement into a victory at the polls. The secular alliance of the Egyptian Bloc and the youth movement Revolution Continues won less than 10 percent of the seats.

The results mirror those from the first round of voting, held in late November, when the two Islamist blocs together won nearly 70 percent.

A third round of voting is to be held Jan. 3-4. It is not expected to alter the result and could strengthen the Islamists’ hand.

The exact number of seats won by each group is not immediately known because of the complicated voting system that Egypt is using. Some seats are determined by a direct competition between candidates, while others are distributed in proportion to each party’s percentage of votes. The commission is to announce the actual number of seats at the end of the entire vote.

The commission also suspended the announcement Saturday of the results for a few seats because of lawsuits filed by candidates who are citing irregularities.

The election is the first since Mubarak’s Feb. 11 ouster and is the freest in Egypt’s modern history. The 498-seat People’s Assembly, the parliament’s lower house, will be tasked, in theory, with forming a 100-member assembly to draft a new constitution.

But its actual role remains unclear. The military council that has ruled since Mubarak’s fall said the parliament will not be representative of all Egypt and should not have sole power over the drafting of the constitution.

Last week, the military appointed a 30-member council to oversee that process.
